Sure Tom. You've got the basics in your outline below. Basically, you
want something like:
Function genDP(original:Array):Array
{
var result:Array = [];
for(var i=0;i<original.length;i++) {
var v:Object = result[i]
result[i] = {
sum: v.apple + v.orange + v.banana,
apple: v.apple,
orangeMin: v.apple,
orangeMax: v.orange + v.apple,
...
}
}
return result;
}
Regarding clustering...you can't tweak the clustering behavior in
ColumnChart, but all the clustering is doing is setting the offset and
columnWidthRatio properties of the individual ColumnSeries objects to
make them line up. So if you used a CartesianChart with some
ColumnSeries in it, you could manually set the offset/columnWidthRatio
properties to whatever you wanted.

Thanks, Ely. Can you point to or provide a simple example of
dataprovider preprocessing?
If my data structure is as follows:
<data>
<result>
<apple></apple>
<orange></orange>
<banana></banana>
</result>
...
</data>
I can see that I need to perform some math on the "result" nodes to
create the new dataProvider:
- add a <total></total> node that is the sum of the "apple" "orange" and
"banana" values
- set the minValue for "orange" as the yValue of "apple', and set the
yValue of "orange" as "apple" plus "orange"
- set the minValue for "banana" as the yValue of "orange" and set the
yValue of "banana" the same as "total"
The "generating chart data" example in the docs seems close, but it's
based on random values rather than manipulating a real xml source.
Another question while I'm at it: is it possible to change the spacing
for just one of four columns in a cluster? I'd like to "total" column to
be separated from the "waterfall" by a space.
